Applied Factor 30 Suncream While Going In Hot, Sunny Weather, Got Burnt, Skin Peeling Off. Treatment?

Hello! I was on a 3 day walk with my friends in late march when, a surprise for us, the weather became very, very hot and sunny. Luckily (even though we d been told not to) one of my friends had brought a small bottle of factor 30 suncream and even though I used some everywhere I could there wasn t quite enough to go round. There was no shelter at all and despite having put suncream on my nose , it still got burnt! And now, 2 months later, it is still peeling and I m getting a bit worried! Do you know what I should do? (Sorry for the essay)
